Title: Magnetic recording medium
Inventor: FURUYAMA SHIZUO
IPC: C09D5/23
Filed: 1986-12-26
Abstract: PURPOSE:To prevent increase in D.O. (drop-out) and generation of cylinder blocking by forming a magnetic layer which is formed by using a metal or alloy magnetic material of >=7.5 pH value and a binder without contg. chlorine atom on a nonmagnetic base. CONSTITUTION:The magnetic layer which is formed by using the metal or alloy magnetic material of >=7.5 pH value and the binder without contg. chlorine atom is formed on the nonmagnetic base. The increase in the D.O. and the cylinder blocking arise as the dehydrochloration is generated from the binder contg. the chlorine atom by preservation. The binder which does not contain the chlorine atom is, therefore, used. A polyurethane resin, polyurethane resin into which a hydrophilic group is introduced, polyester resin, butyral resin, phenoxy resin, etc., are used as the binder without contg. the chlorine atom. The increase in the D.O. and the cylinder blocking are thereby prevented and the durability is improved.

Title: Print controller for electronic photographic printer
Inventor: NAKAZATO HIROHIKO
IPC: B41J5/30
Filed: 1994-11-22
Abstract: PURPOSE: To attain high speed print while preventing an over-run errors. CONSTITUTION: An interface processing section 3 uses a timer 2 to measure a time when a prescribed amount of print data are received from a host device. For example, when the print data are received while a reception buffer 1 is idle by the interface processing section 3, the timer 2 is started and when the print data by a prescribed amount are stored in the reception buffer 1, the timer 2 is stoped to detect a data transfer time. Then a data transfer speed is calculated by dividing number of bytes by the transfer time when a print start control section 4 expands the print data of a prescribed amount into image data for the print. The print start control section 4 adjusts the data transfer speed and the rotation speed of a print drum to coordinate the both.  Furthermore, when the print data by one page are received by a reception buffer 1, the rotationspeed of the print drum 101 is maximized.

Title: Predicate type code processing system
Inventor: ZU-CHIN JU
IPC: G06F9/45
Filed: 1997-11-14
Abstract: PROBLEM TO BE SOLVED: To improve the precision of various compiler analyses and conversion phases by determining areas regarding respective predicates, fractionizing the respective determined areas into mutually prime subsets, and structuring a partition graph on the basis of the respective fractionized areas. SOLUTION: An area with p0 is determined as a master predicate and areas with p4-2 and p5 are determined as slave predicates; and the determined p0 is fractionized into p2 and p3. The fractionized p2 is fractionized into an implicit predicate px generated to complete its partition. Then the implicit predicate px and a 4-1 set union form an area regarding p4-2. Thus, a large-area predicate matching system based upon the partition graph is structured to support many different inquiries regarding predicate type relation. Consequently, the precision and efficiency of various compiler analyses and conversion phases can be improved.

IPC: G03G21/10
Filed: 1995-12-01
Abstract: PROBLEM TO BE SOLVED: To provide an ultrasonic transducer for removing toner from a brush cleaner. SOLUTION: An ultrasonic transducer 10 located under a photoreceptor belt provides vibrational energy to the surface of the belt to separate toner particles 87 from the surface.
